<pre>I'm also having this issue, can help provide any other information required.
It happens completely intermittantly with no trigger that I can pick up.
Usually within 15-60min of boot.
I'm currently passing these kernel params on boot:
i915.preliminary_hw_support=1 drm.debug=0 drm.vblankoffdelay=1
i915.semaphores=0 i915.modeset=1 i915.use_mmio_flip=1 i915.powersave=1
i915.enable_ips=1 i915.disable_power_well=1 i915.enable_hangcheck=1
i915.enable_cmd_parser=1 i915.fastboot=0 i915.enable_ppgtt=1 i915.reset=0
i915.lvds_use_ssc=0 i915.enable_psr=0
Am now testing UXA accel method with Xorg to see if there's any improvement as
someone stated on another site that it may help.</pre>
